He said it was written about Julian, my child. He knew I was splitting with Cyn and leaving Julian. He was driving over to say hi to Julian. He’d been like an uncle to him. You know, Paul was always good with kids. And so he came up with Hey Jude.
But I always heard it as a song to me. If you think about it… Yoko’s just come into the picture.

The words ‘go out and get her’ – subconsciously he was saying, Go ahead, leave me. On a conscious level, he didn’t want me to go ahead. The angel in him was saying, ‘Bless you.’ The devil in him didn’t like it at all because he didn’t want to lose his partner.
‘ Hey Jude’ was first aired in the UK on ‘The David Frost show’, Sunday on September 8th,1968, and the film was later broadcast for the United States on The Smothers Brothers Comedy Hour on 6 October.
‘Hey, Jude’ was actually about Julian Lennon. It was written by Paul at the time John was splitting up with Cynthia. Julian was just a little boy - probably five years old - and Paul had gone out to John’s house and been affected by seeing Julian, the innocent bystander in a divorce situation.
